LAMP

Filed Dec. 4, 1940 INVENTOR HARRY I. ALB/mm- I I gg ATTORNEY5 PatentedApr. 14, 1942 UNITED} STATES rarest errics 1 Claim.

This invention relates to lamps, and more especially it relates toelectric lamps for desk or table use.

The lamp is of especial utility in situations where maximum illuminationis desired, and

where local illumination is desired without the.

necessity for illuminating an entire room or a substantial part thereof.Thus the invention is especially useful for the illumination oftypewriting machines, telephone instruments, drawing boards," and booksand the like.

The chief objects of the invention are to promajor portion of the basebeing flat so as to rest flush upon a desk or other flat surface.

. Close to one of its ends the base 20 is indented vide an improved lamphaving a supporting base I of such construction as to enable articles tobe positioned close to the lamp standard; to provide a lamp having abase of such construction that articles conveniently may rest thereonand thus increase the stability of the lamp; to provide a lamp having abase of relatively simple construction that serves to conceal andprotect the electrical conductor cord of the lamp; and to provide a lamphaving a base that is composed of relatively thin sheet metal, yet whichis firm and rigid. Other objects will be manifest as the descriptionproceeds.

Of the accompanying drawing:

Figure 1 is a vertical sectional view of a from its bottom face toprovide a raised portion 2| that extends from one lateral margin of thebase to the other, said raised portion being substantially square insection so that the top thereof is horizontal and fiat, and is disposedin a plane parallel to the major portion of the base. To reinforce theraised portion 2| and thus to prevent flexure thereof, raised ribs 22,22 are provided, said ribs extending transversely of the raised portionadjacent the ends thereof, and

terminating on the flat portions of the base laterally of the raisedportion and closely adjacent the same.

The horizontal top wall of the raised portion 2| is centrally aperturedto receive a tubular ferrule 24 that is secured therein, and the lowerend of the standard member ID is threaded into the upper end of saidferrule so that the standard is supported thereby. The conductor cordlamp embodying the invention, the lamp shade being shown in elevation;and 1 a Figure 2 is a plan view of the improved lamp as seen from theline 2-2 of Fig. 1.

Referring to the drawing, there is shown a telescopic lamp standardcomprising a tubular lower member ID and a tubular upper member II, thelatter being disposed partly within the member Ill. The upper end ofmember III has a collar I2 threaded thereon through which the member Hslidably extends, and a thumb screw I3 is threaded radially through saidcollar for engagement with said member H to retain the latter inproperly adjusted axial position with relation to member [0. The memberI I is formed with a longitudinally extending flat surface Ila on oneside thereof, which surface is engaged by the thumb screw l3, thearrangement being such as to prevent angular movement of the member Hwith relation to the member ID. Threaded onto the upper end of member IIis an elbow l4, and supported by the latter, at right angles to thestandard, is a C-shaped bracket l5, the arms of which extendhorizontally outwardly. The free ends of said bracket arms between themsupport a lamp shade l6, and within the latter is the usual lamp socketand lamp bulb (not shown). The conductor cord l1 extends from the saidsocket, through the elbow I4, and through the standard members II andIll, said cord emerging from the latter at the bottom thereof.

The lamp standard is carried by a base 20 composed of relatively thinsheet metal, said base preferably being of oblong shape as shown, the

ll extends through the ferrule 24 and into the space below the raisedportion 2|, the latter thereby constituting a tunnel for the cord toguide the same laterally and away from the major portion of the. baseupon which articles may rest. The shade l6 and the major portion of thebase 20 are determinately positioned, with the lamp bulb directly oversaid base.

When in use, articles may rest upon the thin, fiat base 20, as indicatedby broken lines at 25, Fig. 1, without being tilted thereby, yet may bepositioned so close to the standard as to obtain maximum illuminationfrom the lamp thereon. Articles resting upon the base 20 serve to retainthe latter in desired position, and also serve to prevent tilting orupsetting of the standard. The improved lamp is of relatively simpleconstruction and achieves the other advantages set out in the foregoingstatement of objects.

Modification may be resorted to without departing from the spirit of theinvention or the scope thereof as defined by the appended claim What isclaimed is:

A lamp comprising an upright standard, and a base for said standard,said base consisting of a one-piece structure'of relatively thin sheetmetal of oblong shape formed with a transverse raised portion adjacentone end thereof extending from one lateral margin to the other, saidraised portion being open at its ends and comprising a fiat horizontaltop wall upon which said standard is centrally mounted, and flat frontand rear walls disposed perpendicular to the main body of the base, saidfront wall constituting a stop means adapted to align papers and thelike that may rest on the base, said raised portion constituting atunnel for a conductor cord which extends into said standard.
